BRIsTLE MAGAZINE FOR BRUSH MAKING AC INES Application filed February 11,1929. Serial No.' 338,979.

My invention relates particularly to bristle magazines adapted to be used in connection with brush-making machines, and designed for insertion in and use in connection with" providing a bristle magazine which eliminates mussing of the bristles and which, once the bristles are placed in position the latter, will be uniformly fed to the machine without disturbance or displacement of any kind.

My invention is applicable, for example, to a brush-making machine, as set f-orthin the patent to Gane No. 378,130, granted February 21, 'lerhune upon machine for making brushes, No. 1,448389, granted March 13, 1923.

Further objects of my invention will appear from the detailed description of the same hereinafter. v. p

lVhile my invention is capable of embodiment in many different forms, for the purpose of illustration I have shown only one form in the accompanying drawings, in which Fig. 1 is a diagrammatic plan view of a bristle magazine made in accordance with my invention;

2 is a side elevation of the same;

Fig. 3 is an end elevation thereof; and

Fig. 4; is a vertical section of adetail.

In the drawings, I have shown a magazinecarrying frame 1 which is movably supported upon a main frame 2 of a brush-making machine such as is shown in the patent to Gane above referred to. This frame 1 has supported therein a reel 3 on a pivot 4: which carries wound thereon two narrow strips of spring steel 5 and 6 which may, if desired, be made of steel wire instead, between which there is carried tightly compressed a layer 7 of transversely arranged bristles which have been introduced between the two strips 1888, or the patent to Loomis and sure helical form on the reel3. Thefouter ends of the strips 5 and GjareLcarried around and attached to two similar reels, respectively, Sand 9, splined loosely by means of slots 8a and 9a, to allow lateral movement thereof, upon shafts l0.and-11 in the magazine frame 1-. I These shafts l0 and 11 have also removable bushings 100a' and 11a projecting into the frame 2 attheir lower ends and; clips 10?) and 116, with an interposed spring 100 at their upper ends to draw the reels 8 and 9 together. .Thesereels 8 and 9qare provided underneath the frame v1 with reels12 and13 supported in a bracket 13a, and which are moved by weightsl, 15 attached thereto by cords 14a, 15apassing over pulleys 16', 16a

on the frame 2 for feeding. the bristles to the v the clips 106, 100 and replaced by a new reel fully charged when the supply of bristles has been quite, "or: almost, exhausted from the particular magazine. As shown in Fig.

1, the magazine frame 1 is sopositioned by the pivots 4i, 10and l1 resting within corresponding recesses in the frame 2, that-itwill.

remain fixedly in pla'ceduring the operation of the machine, and will feedthe bristles into channel 17 provided in the main frame which a picker knife21 and picker21a operate for conveying the bristles into a slot 22 in aninserting nozzle 28 provided with a reciprocating needle 24-arranged to inject an anchor. into the nozzle 23 through 'a slot 26, as well as said bristles; from the slot 22, out of an end 27 of said nozzle. into'a hole in the brush blank which" hasbeen provided for the anchoring of the tuft of bristles by the anchor insaid hole of the brush blank. The operation of these parts is conducted in the samemanner as in the said patent to Gane above referred to.

By this means, owing to the fact that there is no interference whatever. with the position of the individual bristles during the flow of the same from the magazine to the picker, the bristles will always be in the proper position throughout the feeding operation thereof and will not be subjected to the mussing which occasionally or often occurs in previous magazines utilizing combs or other bristle moving mechanism. Consequently, by the utilization of magazines made in accordance with my invention the maintenance of the brush-making machine is much more readily maintained and the disadvantages and losses due to shutting down the brushmaking machine are" thereby largely'eliminated. The importance of this willbe readily appreciated considering the high cost of l. A brush a fibre magazine comprising a mechanism including areciprocating picker for feeding the fibres, and means for transferring the fibres from the body of fibres in the magazine to the point of delivery to the picker without disturbance of the relative position of the fibres during the feeding operation, comprising a spiral flexible re- 5 taming means for the body of fibres.
